The invention relates to a reflection type energy selection structure, belongs to the technical field of material regulation and control, and solves the problems of poor protection effect and easy damage of a reflector antenna in the prior art. The reflection type energy selection structure comprises at least one layer of metasurface structure, a diode and a power supply. The metasurface structurecomprises a plurality of metal resonance units arranged in a two-dimensional array, each metal resonance unit comprises n metal sheets arranged in a one-dimensional array, and n is larger than or equal to 3 and smaller than or equal to 10; adjacent metal sheets in the metasurface structure on the outermost layer are connected through diodes. The power supply is used for supplying power to the diode; when a high electromagnetic pulse is incident, the metasurface structure is used for changing the phase of the high electromagnetic pulse, so that the reflected high electromagnetic pulse is deflected to deviate from the feed source, and therefore, system electronic equipment at the feed source of the reflector antenna can be effectively protected, and the system electronic equipment can be prevented from being damaged by the incident electromagnetic pulse.
Description
technical field [0001] The invention relates to the technical field of material control, in particular to a reflective energy selection structure. Background technique [0002] With the continuous development of information technology, the degree of electronicization of information systems is getting higher and higher, and the sensitivity to electromagnetic fields is also getting higher and higher. Electromagnetic pulses have a certain impact on these electronic devices to a certain extent, and can affect electronic system equipment. Cause certain damage, lead to damage to the entire system equipment, resulting in huge losses, so the protection of the system is an urgent need to consider. In order to solve these problems, the measure of energy selective surface has been proposed in recent years, which is mainly aimed at the protection of circuit devices according to different purposes when electromagnetic fields of different strengths are incident. [0003] At present, on t...
